How much water do I add to a 5 mg BPC-157 vial?

The water amount is your choice, it only changes how strong each mL is. With 2 mL you get 2.5 mg per mL; with more water each unit holds less, which makes small doses easier to measure.

How many units is 1 mg of BPC-157?

It depends on the strength of your mix. At 2.5 mg/mL, 1 mg is 40 units. Enter your own vial and water in the calculator to get your number.

How long does mixed BPC-157 keep?

Follow the storage line on your product or prescription. Bacteriostatic water itself should be used within 28 days of the first needle, per CDC guidance.

Enter the BPC-157 vial size, the water amount you added and your dose to see how many units to draw with a U-100 insulin syringe.

Just for reference. Your prescriber sets your dose, or the product label does; we only convert it here to units.

Available vial sizes: 5 mg, 10 mg, 15 mg
status of approval: Not FDA-approved.
Example: 2 mL added to 5 mg: 2.5 mg/mL strength

Working out BPC-157 math

You get strength by dividing the amount in the vial by the water. Each mL contains 2.5 mg when a 5 mg vial has 2 mL of water. The mL amount comes from dividing your dose by that strength. For a U-100 syringe, multiply that result by 100 for units.

From that vial, 50 mcg equals 0.02 mL, or 2 units.
